Our partners

Thanks to the financial and technical support of our partners, the Seinoscope is now equipped with new information panels. No fewer than 18 panels to learn more about the fish in the Seine and how the Seinoscope works.


The Seinoscope, located near the Poses dam, allows visitors to see the many species of fish that swim up the Seine. Quite simply, it is the only viewing chamber on the Seine open to the public. It consists of a room with three picture windows, below water level, overlooking the pass. In addition, there is a vision chamber for scientific monitoring of the number of migratory fish each season, via video-counting.

Visits for the general public :

Saturdays to Sundays and public holidays ONLY at the following times:

  • 2pm - 6pm

Visits for groups: We offer guided tours with a qualified guide for schools, associations, leisure centres, companies, etc. These 1.5-hour guided tours include the Seinoscope, the dam, the hydroelectric power station and the Poses locks.

Wherever possible, our timetables can be adapted to suit your requirements, so don't hesitate to give us a call.
